VALVE FOR OIL-BURNERS.

Application filed August 10, 1918, Serial No. 249,217. Renewed October19, 1920.

To all whom it may concern e it known that I, Jnssn D. HORTON, a citizenof the United States, residing at New York, in the county of Bronx andState of New York, have invented certain new and useful Improvements inValves for Oil-Burners; and I do hereby declare the following to be afull, clear, and exact de scription of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

lue flame oil stoves have been constructed hitherto wherein means areemployed whereby the oil is converted into gas by heat before reachingthe burner. In order to light these stoves a small preliminaryquantity-of oil is supplied and is caught in a suitable receptacle closeto that portion of the burner in which the oil is subsequently convertedinto gas during operation of the stove. Upon lighting this preliminarydose of oil with a match, a flame is produced which acts to heat up theapparatus until the oil coming to the burner is converted into gas andis ignited, afterwhich the burner maintains its own gas-producingtemperature, and continuous operation of the burner is insured. A

In stoves having burners of this kind it has been customary to controlthe supply of oil by means of a needle valve, which is first openedwide, to permit passage of the preliminary volume of oil for lighting;and, after the blue flame is produced, is almost closed, so as torestrict the oil supply to the very small volume necessary to maintainthe blue flame.

The manipulation of the needle valve for the double to say forpreliminary lighting and subsequent throttling down of the supply, involves a degree of expert judgment too often found absent in the classof persons to whom it is necessary to confide the management of theseoil burners. Consequently, stoves supplied with such burners are oftenfound wasteful and offensive, and are he quently subject to'seriousaccidents, owing to the careless or ignorant use of the valve. It is theobject of my present invention to supply a form of burner which shallmake available all the advantages of the needle valve for accurateadjustment and readjustment of the supply, while rendering itunnecessary to manipulate such valve in the preliminary lightingoperation. The han- Specification of Letters Patent.

purpose of full control, that is volume of lighting fluid is at PatentedNov. 30, 1920.

Serial No. 418,096.

dling of the valve by ignorant or unskilled labor thus becomesunnecessary, vention supplies means at the same time whereby thepreliminary lighting oil is supplied in exactly the right volume. Myinvention thus acts at once to prevent accidents and waste.

My invention is illustrated in a preferred form in the accompanyingdrawings, wherein Figure l is a side elevation showing the location ofmy burner valve with relation to any appropriate burner, Fig. 2 a sideelevation of the valve itself on a larger scale, and F 1g. 3 is avertical section of the burner valve. 7 At 10 is shown any appropriatestove having a blue flame oil burner, to which fuel is supplied thro ghthe pipe 11. The oil reaches this pipe from any appropriatereservoir(not shown) by means of a pipe 12, and a cylindrical antechamber 13between the pipes 11 and 12. The antechamber 13 is preferably of glass,so that the supply of oil therein may be'observed.

Between this antechamber and the burner provide means of any desiredcharacter whereby communication between the two may be entirely out ofl;and for this purpose I preferably employ a stop cook 14.

The supply of oil from the pipe 12 to the chamber 13 is controlled bythe needle valve 15.

In operation the needle valve is set once for all by a properly skilledperson, so as to supply the oil drop by drop for normal use. It isnot'operated by the person using the stove. If there is any momentaryclogging or other need for readjustment, a skilled person may be calledupon to use the needle valve for this purpose. When the burner is not inuse the stop cock 1% is closed and the chamber 13 gradually fills up.lVhen it is full, the proper quantity of oil for lighting as abovedescribed is stored in this antechamber. When the burner is to belighted it is only ne'cessary to open the cook 14, when the proper oncereleased and can be ignited at once in the proper re ceptacle. By thetime this volume is ex hausted the burner is sufliciently heated toproduce the blue flame, and any subsequent oil supply is suitablylimited by the needle valve.

It will thus be seen that, in using my valve and urner it is onlynecessary to open a simple stock cock to its full extent when lightingthe stove, and to close the same when extinguishing the flame. Theamount of lighting oil is not left to the judgment of the user, and thenormal supply during use is also regulated once for all, and independently of the preliminary supply.

Various changes may be made in my device without departing from thescope of my invention, and I do not limit myself to the details hereinshown and described.

What I claim is In combination with an oil burner, oil

feeding means therefor comprising a chamber of size suitable to containthe oil for its preliminary lighting, inlet and outlet passages andbeing otherwise entirely closed, an adjustable needle valve in the inletpassage, a pipe from the outlet passage to the burner, and means adaptedentirely to cut: off communication between said chamber and said burnerat wi l. i

said chamber having 7 In testimony whereof I afiix my signature.
